Quantum computers are nowhere near usable for breaking classical cryptography at the moment, though opinions on how soon it will come vary. As others have said, we have quantum resistant algorithms ready to go, so future encryption is fine.
The greater concern is that a lot of traffic and data encrypted using classical algorithms has been logged or stored in various mediums. An old encrypted drive, or communications stored by nation state actors (the NSA and such). These will be broken, and a lot of past secrets might come out from hiding.
It reminds me I could store my public key in the avatar. We may have to make things more difficult with steg.
I assume it’s inevitable and there are people working on a solution. That aside, I’m pretty excited to see what quantum computing will be capable of in our lifetime.
It’s been known to be an issue for a very long time now. It is what it is. Nothing is going to change the fact that my data will be decrypted.
I’ll believe it when I see it. There’s a long, long way to go between current quantum tech and something that can crack modern 4096-bit RSA.
And honestly, it’ll probably come so slowly that we’ll have all switched to better algorithms by the time RSA cracking becomes feasible. (Yeah, I know about store now decrypt later, but that won’t really affect the average person if it takes decades to come to fruition.)
